The theme for this month is "Juxtaposition", as chosen by Trevor Harris who won our February competition.

Be sure to read the whole post for the rules.

In Trevor's words:

There are many technical reasons that capture my eye in photos, color, composition, lead lines… I suspect the majority of users here tend to the same reasons based on the generally male demographic. But in the interest of stepping outside our comfort zones, I'm going to choose something a bit more artsy for us to lean towards. I'm choosing Juxtaposition for Aprils theme.

Explore this theme in whichever niche of photography way you wish. People, still life, landscapes. I'm not going to list any restrictions on post processing, but as EvanK so eloquently put a few months ago, "please do us all a favour and stay away from any super overdone HDR".

Now, get out there and shoot!

Great choice, Trevor! Something to get us all thinking about how to use our cameras to say something about the world around us.

The rules!

1: You can only submit one image and it MUST be taken during April 2013. Photos taken earlier will be disqualified!

2: All images submitted must be no more than 1024 pixels on their longest side, although you can include a link to a full resolution version if you like. Flickr users must link back to the original version to comply with its latest rules.

As always, please exercise good judgement on what is suitable for the forum. Keep it clean and family-friendly or it'll be removed. See the Forum Rules if you are unsure.

Please include a sentence or two with your photo describing what you were trying to achieve and if there were any particular challenges in doing so like, for example, any special exposure or lighting setup.

We're all enthusiasts here, so it's also great to see what equipment you used and the settings too. So please also include the following:

THE PRIZEIn March, I (Bjorn) offered the winner of the competition a prize. However, the condition that there had to be at least 20 entries was not met. Thus, the prizewill be available for April's competition, with the same conditions. Grab yourcamera, go out (or stay in, depending on your idea), and shoot your submissionfor April.

So, what is the prize? It's a copy of Joe McNally's "The moment it clicks", a great book about photography describing the stories behind some of Joe's images. Goes for over $30 on Amazon, but you can get it for free. I will even pay for the shipping myself, which is why I will only do this once, shipping charges can get crazy here in Holland.

Again, there is one condition: there have to be at least 20 entries. If there aren't, I might consider moving the prize to next month, or not offer it anymore and keep the book for myself, I'm not sure yet.

So, if you want a chance to win a free photography book, submit an entry tothis month's assignment themed "Juxtaposition". You have until the end of the month as always. Good luck!

I hope this qualifies for Juxtaposition. And it was taken April 1 so its a start on April.Canon 5d Mk III, Lens - 35mm Sigma Prime. F/5.6 at 1/125 Sec and ISO 8000. Taken at the Huntington Library in San Marino, CAand they do not allow flash.

We have attempted to create our own Zen garden at home, I'm sure that the Japanese would be horrified at our efforts because we almost certainly break all the rules and so drive a cart and horses through the underlying philosophy. We regularly strongly disagree about tiny changes in the placement of the components, so there must be more to this juxtapositioning malarkey than we at first realised!

I've been spending quite a while up in Liverpool this year and really enjoying the classy old buildings at the waterfront around Albert Dock. Around the same area are a number of new buildings including the Museum of Liverpool complete with large shiny windows. I was passing on a sunny day near the beginning of April and noticed some nice reflections of the older buildings opposite, so adjusted my position until I saw what looked like a nice repetition of patterns, along with a framing which included the word Liverpool.

It's pretty contrived I admit: the reflection of one building in the windows of the other, but I love the effect and thought it made a nice juxtaposition. I actually took this without registering what the theme for this month's assignment was, but by luck it hopefully fits the bill!

Photography journey. This picture shows the summary of my journey through photography. It started with a 3.2MP Sony Cybershot (DSC-P32) and continues today with the M9-P. Used my favorite book Elliott Erwitt XXL Special Edition as a background, since Erwitt has been such an important source of inspiration for me.

I was out looking for a much different image than this since my goal was to shoot a local bridge. As I passed underneath this crow I thought that the bird in the lower left and the moon in the upper right would be good composition. I shot several from the same vantage point with the crow in focus then again with the moon in focus. The most interesting image of the crow was overlaid with the sharpest image of the moon.

Camera Model: Canon EOS Digital Rebel XT -- nothing spectacularLens and focal length: Tamron 28-200mm F/3.8-5.6 LD AsphericalAperture: f/10.0Shutter Speed: 1/50sSensitivity: ISO100Post processing: I prefer open source software on Linux whenever possible. The RAW images were imported via RawTherapee. The best crow and moon images were opened as layers into GIMP 2.6. Slight adjustments to levels were made. Overlaid the focused moon onto the focused crow. Carefully blend the sharp moon to better match the tone of the sky then sharpen the moon only. I came up with two versions and I asked my daughter to pick her favorite which you see here.

Rotary won this time, not that the plane had much of it's wings left! The occasion was the last "flight" of a Gloster Meteor T7 from Imjin Barracks to its final resting place at the Gloucestershire Jet Age Museum at Staverton Airport. I was working with the camera held as high as possible above my head to avoid an eight foot wire mesh fence. As a result framing was difficult and, after initial focussing, I disabled the camera's AF and shot in bursts. Out of about 50 frames three were usable! Processing in Photoshop was essentially confined to pulling out some shadow detail, while retaining as much contrast as possible from a very flatly lit day, plus noise reduction. I considered correcting the "horizon" but in the end I retained the greater sense of motion.
